Feel free to get creative! Some great add-ins include sauteed spinach, caramelized onions, or even a handful of chopped fresh parsley for a pop of color.

Deb’s tips
You can serve these breasts whole, or you can shred them for a more pulled chicken consistency.
- For a little more flavor, season your chicken with chicken seasoning mix on both sides before adding it to the slow cooker.
- Make dishes easier on yourself by using a slow cooker liner. Then washing up will be a snap.
